CME & CBOT RA1204-3

Notice Date

29 October 2012

Effective Date

07 November 2012

This Advisory Notice supersedes CME & CBOT Market Regulation Advisory Notice RA1203-3 from October 24, 2012. It is being issued to notify the marketplace that pending all relevant regulatory review periods, effective on trade dateNovember 13, 2012, CBOT will launch its suite of US Dollar Interest Rate Swap (“USD IRS”) futures contracts, all of which will become block eligible. Each of these proposed new futures contracts will expire by physical delivery of a standardized Libor-reference interest rate swap (IRS), with term to maturity at delivery of 2, 5, 10, or 30 years, that is cleared and guaranteed by CME Clearing. Upon launch, block trading will be allowed in the new USD IRS futures products at the following minimum threshold contract levels:

2-Year USD IRS futures - 3,000 contracts

5-Year USD IRS futures - 1,500 contracts

10-Year USD IRS futures - 1,000 contracts

30-Year USD IRS futures - 500 contracts

Additionally, as previously communicated in CME & CBOT Market Regulation Advisory Notice RA1203-4, and pending all relevant regulatory review periods, the following changes will become effective on trade date November 7, 2012:

1)Revisions to CME and CBOT Rule 526 that clarify that unless otherwise agreed to by the principal counterparties to the block trade, the price reporting obligation is the responsibility of the seller, or, in the case of a brokered transaction, the broker handling the block trade (see Section 5b); and

2)Clarifications pertaining to prohibited disclosure and the use of non-public information related to block trades (see Section 10).

CME and CBOT products in which block trading is permitted appear in Section 12, and the text of CME and CBOT Rule 526 appears in Section 14 of this Advisory Notice.

1. Definition of Block Trades

Block trades are privately negotiated futures, options or combination transactions that meet certain quantity thresholds which are permitted to be executed apart from the public auction market. All block trades are subject to the conditions set forth in CME and CBOT Rule 526 and in this Advisory Notice. Additionally, BTIC block trades in Select Sector futures and DJUSRE futures are also subject to the requirements set forth in CME Rule 36906.A. (“BTIC Block Trade Requirements”) or CBOT Rule 30107.A. (“BTIC Block Trade Requirements”), as applicable. Additional information on BTIC block trades appears in Section 9 of this Advisory Notice.

2. Participation in Block Trades

Each party to a block trade must be an Eligible Contract Participant as that term is defined in Section 1a of the Commodity Exchange Act. Eligible Contract Participants generally include exchange members and member firms, broker/dealers, government entities, pension funds, commodity pools, corporations, investment companies, insurance companies, depository institutions and high net-worth individuals. Commodity trading advisors and investment advisors who are registered or exempt from registration, and foreign persons performing a similar role and subject as such to foreign regulation, may participate in block transactions provided they have total assets under management exceeding $25 million and the block trade is suitable for their customers.

A customer order may be executed by means of a block trade only if the customer has specified that the order be executed as a block trade.

Orders may not be bunched to meet the minimum block quantity thresholds.

3. Time and Prices of Block Trades

Block trades may be executed at any time, including times during which the public auction market is closed, except that BTIC block trades may not take place on the last day of trading in an expiring contract month.

Block trades must be transacted at prices that are “fair and reasonable” in light of (i) the size of the transaction, (ii) the prices and sizes of other transactions in the same contract at the relevant time, (iii) the prices and sizes of transactions in other relevant markets, including, without limitation, the underlying cash market or related futures markets, at the relevant time, and (iv) the circumstances of the markets or the parties to the block trade.

The Basis applied to a BTIC block trade must also be fair and reasonable taking into account financing rates, expected dividend income and the time remaining until the applicable futures contract expires pursuant to the requirements of CME Rule 36906 (“Basis Trade at Index Close (“BTIC”) Transactions”) or CBOT Rule 30207 (“Basis Trade at Index Close (“BTIC”) Transactions”), as applicable.

The trade price must be consistent with the minimum tick increment for the market in question. Additionally, each outright transaction and each leg of any block eligible spread or combination trade must be executed at a single price.

Block trade prices are reported independently of transaction prices in the regular market and are not included as part of the daily trading range. Block trade prices do not elect conditional orders (e.g. stop orders) or otherwise affect orders in the regular market.

The block trade minimum quantity requirements for outright futures and options are set forth in the list of block trade eligible products in Section 12 of this Advisory Notice. Additional information with respect to spreads and combinations executed as blocks appears below:

Intra-commodity futures spreads and futures combinations may be executed as block trades provided that the sum of the quantities of the legs meets the minimum block quantity threshold. For example, 2,000 Eurodollar future calendar spreads executed during RTH hours would meet the Eurodollar futures minimum quantity requirement of 4,000 contracts.

Intra-commodity calendar spread block trades are prohibited in CBOT U.S. Treasury futures, OTR Treasury Yield and 5-, 7-, 10- and 30-YearInterest Rate Swap futures. Parties may not execute contingent block trades in outright contracts to circumvent the prohibition on the execution of block trades in intra-commodity calendar spreads. Additionally, Tandem spreads (a trade combining calendar spreads in two different Treasury futures) may not be executed as block trades.

iii) GSCI Futures

In GSCI futures and GSCI Excess Return Index futures the block trade minimum is 300 contracts for each leg of the spread or combination. For example, the minimum quantity for a GSCI calendar spread would require 300 contracts in each leg of the spread for a total of 600 contracts while a GSCI futures butterfly would require a minimum volume of 1,200 contracts.

b) Inter-Commodity Futures Spreads

i) Short Term Interest Rate Futures

In Short Term Interest Rate futures (Eurodollars, Eurodollar E-minis, Euribor, T-Bills, OIS, One-Month Eurodollar, Euroyen and 30-Day Fed Funds), inter-commodity futures spreads may be executed as block trades provided that the sum of the legs of the spread meets the larger of the threshold requirements for the underlying products. For example, the minimum quantity thresholds for One-Month Eurodollar and Eurodollars during ETH are 200 and 2,000 contracts, respectively. Therefore, a block trade in the One-Month Eurodollar/Eurodollar spread can be executed provided that the sum of the legs is at least 2,000 contracts.

In U.S. Treasury, OTR Treasury Yield, 5-, 7-, 10- and 30-Year Interest Rate Swap and 10-Year Sovereign Yield Spread futures, inter-commodity futures spreads may be executed as block trades provided that each leg of the spread meets the minimum threshold requirement for the respective underlying products. For example, the minimum quantity thresholds for 10-Year Notes and U.S. Treasury Bonds during RTH are 5,000 and 3,000 contracts, respectively. Therefore, a block trade in the NOB spread (10-Year Note/Treasury Bond spread) can be executed only if the minimum quantity of the 10-Year Note leg of the spread is at least 5,000 contracts and the minimum quantity of the Treasury Bond leg of the spread is at least 3,000 contracts.

iii) USD IRS Futures

Inter-commodity futures spreads or combinations composed only of USD IRS futures (e.g., 2-Year USD IRS v. 10-Year USD IRS) may be executed as block trades provided that the sum of the legs of the spread meets the larger of the threshold requirements for the underlying products. For example, the minimum block trade thresholds for 2-Year USD IRS futures and 10-Year USD IRS futures are 3,000 and 1,000 contracts, respectively. Thus, a spread between these two contracts may be executed as a block trade if the sum of the quantities of the legs is at least 3,000 contracts.

Inter-commodity futures spreads or combinations excluding those composed only of USD IRS futures (e.g., 10-Year Treasury Notes v. 10-Year USD IRS) may be executed as block trades provided that each leg of the spread meets the minimum threshold requirement for the respective underlying products. For example, the minimum block trade thresholds for 10-Year Treasury Note futures and 10-Year USD IRS futures during RTH are 5,000 contracts and 1,000 contracts, respectively. A spread between these two contracts can be executed as a block trade, therefore, only if the quantity of the 10-Year Treasury Note leg is at least 5,000 contracts and the quantity of the 10-Year USD IRS leg is at least 1,000 contracts.

iv) All Other Products

In all other block-eligible products, inter-commodity futures spreads may be executed as block trades provided that the quantity of each leg of the spread meets the larger of the threshold requirements for the underlying products.

c) Intra-Commodity Option Spreads and Combinations

Intra-commodity option spreads and combinations may be executed as block trades provided that the quantity of each leg of the spread meets the designated minimum quantity threshold.

d) Inter-Commodity Option Spreads and Combinations

Inter-commodity option spreads and combinations may be executed as block trades provided that the quantity of each leg of the spread meets the larger of the threshold requirements for the underlying products.

e) Options/Futures Spreads

In general, options/futures spreads may be executed as block trades provided that the options component of the spread meets the minimum quantity threshold for the outright option or option combination and the quantity of futures executed is consistent with the delta of the options component of the spread. An exception applies to Weather and Housing options/futures spreads, where the legs of the spread may be summed to meet the 20-contract minimum threshold.

5. Block Trade Price Reporting Requirements

a) Time Requirements

With the exceptions noted below, all block trades must be price reported to the Exchange within five minutes of the transaction.

i) Block Trades during European or Asian hours (ETH or ATH) in Interest Rate

Products Excluding USD IRS

Interest rate block trades executed during ETH or ATH must be price reported to the Exchange within 15 minutes of the transaction. With the exception of USD IRS, interest rate block trades executed during RTH must be reported within five minutes.

ATH: 4:00 p.m. – 12:00 a.m. CT, Monday through Friday on regular business days and at all times on weekends

ii) Weather, Housing, and USD IRS Block Trades

Block trades in Weather, Housing and USD IRS contracts must be price reported to the Exchange within 15 minutes of the transaction.

b) Reporting Obligation

Price reporting obligations are the responsibility of the seller, unless otherwise agreed to by the principal counterparties to the block trade; however, in the case of a brokered transaction, the price reporting obligation is the responsibility of the broker handling the block trade, unless otherwise agreed to by the principal counterparties to the block trade. For purposes of the foregoing, the term “seller” refers to the principal counterparty acting as the seller of the block trade.

The failure to submit timely, accurate and complete block trade reports may subject the party responsible for the reporting obligation to disciplinary action. Parties shall not be sanctioned for block reporting infractions deemed to arise from factors beyond the reporting party’s control (e.g. the block trade fails the CME ClearPort automated credit check.)

c) Reporting Methods

Block trades must be price reported to the Exchange via one of the following methods.

i) Globex Control Center (“GCC”)

All block trades (except for BTIC block trades in CME Select Sector futures and CBOT DJUSRE futures and block trades in Weather futures and options executed between 8:00 a.m. and 3:30 p.m. Chicago time, Monday – Friday on regular business days) may be price reported to the GCC. The seller or broker reports the trade by calling the GCC at 312.456.2391. When the GCC is closed – for example, during the weekend – the block trade must be reported no later than five minutes prior to the opening of the next electronic trading session for that product.

Block trades in Weather futures and options executed between 8:00 a.m. and 3:30 p.m. Chicago time, Monday – Friday on regular business days should be price reported to Exchange staff by calling 312.648.3935 or 312.648.3936.

d) Information Required When Reporting Block Trades

When price reporting a block trade, the following information will be required:

Contract, contract month and contract year for futures, and, additionally for options, strike price and put or call designation for standard options, as well as the expiration date and exercise style for flex options;

Quantity of the trade or, for spreads and combinations, the quantity of each leg of the trade;

Price of the trade or, for spreads and combinations, the price of each leg of the trade; and

Buyer’s clearing firm and seller’s clearing firm;

Name and phone number of the party reporting the trade (unless the block trade is electronically reported); and

Execution time (in Central Time) of the trade (i.e. the time at which the trade was consummated).

6. Block Trade Submission Requirements to CME Clearing

Block trades price reported to the GCC or Exchange staff as described in numbers i) or iv) above must be submitted to CME Clearing through the FEC User Interface via the portal under BLOCK entry. For block trades executed between 6:00 a.m. and 6:00 p.m. Central Time, firms must submit the trade within one hour. For block trades executed between 6:00 p.m. and 6:00 a.m. Central Time, firms must submit the trade no later than 7:00 a.m. Central Time.

Block trades are entered by both the buyer’s and seller’s clearing firm and go through a two-sided match process. Upon entry, confirmation records will be routed back to the firms for bookkeeping purposes. When reporting spread or combination transactions, each leg must be entered individually. The execution time is required to be entered and must be the actual time at which the transaction was consummated by the two parties, not the time at which the trade is reported by the parties to their respective firms. Thus, if the clearing member has not acted as either principal or agent in the transaction, it must ensure that its customer provides an accurate execution time.

A block trade in a block-eligible option may be executed up to and including the day on which an option contract expires for purposes of offsetting an open option position. The offsetting block trade must be price reported to the GCC pursuant to the requirements of section 5 above, and the offset must be submitted to CME Clearing no later than the Position Change Submission (“PCS”) deadline on the day on which the option contract expires. The current PCS deadline is 7:30 p.m. Central Time.

7. Block Trade Recordkeeping

Complete order records for block trades must be created and maintained pursuant to Rule 536 and CFTC Regulations. Additionally, the time of execution of the block trade must also be recorded for all block trades.

8. Dissemination of Block Trade Information

The date, execution time, contract details, price and quantity of block trades are reported upon receipt of the block information by GCC. Block trade information is reported on the MerQuote system and may be accessed by entering the code “BLK”. The information will also be displayed on cmegroup.com at the following link: http://www.cmegroup.com/tools-information/blocktrades.html. Block trade information is also displayed on the trading floor.

Block trade prices are published separately from transactions in the regular market.

Block trade volume is also identified in the daily volume reports published by the exchange.

9. BTIC Block Trades

A BTIC Transaction is a futures transaction that is priced with reference to the applicable cash index close price. BTIC Transactions in Select Sector futures and BTIC Transactions in DJUSRE futures may be executed as block trades pursuant to the requirements of Rule 526 (“Block Trades”), this Advisory Notice and the applicable provisions in the corresponding product chapter (CME Chapter 369 for Select Sector futures and CBOT Chapter 30 for DJUSRE futures).

The current minimum threshold of 50 contracts applicable to each product will also apply to BTIC block trades in the products. BTIC block trades will not be permitted on the last day of trading in an expiring contract month.

BTIC block trades may not be executed as a spread transaction pursuant to the requirements in Section 4 of this Advisory Notice. Parties wishing to effectuate a block spread transaction in either product will be required to negotiate the transaction as separate outright BTIC block trades, and each leg must meet the minimum threshold of 50 contracts.

The futures price assigned to a Select Sector futures BTIC block trade will be based on the current day’s Select Sector cash index close price, or the current day’s Select Sector cash index close price adjusted by any valid price increment (the “Basis”) higher or lower than the Select Sector cash index close price. The Basis must be stated in full tick increments as set forth in CME Rule 36901 (“Commodity Specifications”).

The futures price assigned to a DJUSRE futures BTIC block trade will be based on the current day’s Dow Jones US Real Estate cash index close price, or the current day’s Dow Jones US Real Estate cash index close price adjusted by any valid price increment higher or lower than the Dow Jones US Real Estate cash index close price. The Basis must be stated in full tick increments as set forth in CBOT Rule 30102 (“Trading Specifications”).

Market participants that transact BTIC block trades should be aware that the only acceptable method for price reporting and submitting BTIC block trades to CME Clearing is through CME ClearPort, and the entry of the trade into CME ClearPort must occur within five minutes of the agreement of the parties to execute the trade in order to comply with the price reporting requirements of CME Rule 526.F. It is not permissible for market participants to price report BTIC block trades to the Global Command Center (“GCC”) and separately enter the block trades into Front-End Clearing (“FEC”) as is allowed for other block trades in CME and CBOT products. Market participants should also be aware that entry of block trades into CME ClearPort requires registration. Additional information on registration for CME ClearPort is available on the CME Group website.

BTIC block trades must be reported to the Exchange via CME ClearPort at least 10 minutes prior to the scheduled close of the underlying primary securities market to establish the BTIC futures price on the current trading day. A BTIC block trade that is not reported at least 10 minutes prior to the scheduled close of the underlying primary securities market will be priced based on the index close price for the next available trading day for the primary securities market.

The futures price of a BTIC block trade will be determined by the Exchange at 3:45 p.m. Central Time and the Exchange-determined price will be final at that time. In the event of an early scheduled close of the primary securities market, the futures price of a BTIC block trade will be determined by the Exchange 45 minutes after the early scheduled close time for the primary securities market, and the Exchange-determined price will be final at that time. In the event of an equity market disruption in the primary securities market, all BTIC block trades will be cancelled for that trade date.

Parties involved in the solicitation or negotiation of a block trade may not disclose the details of those communications or any non-public information regarding a consummated block trade to third parties.

Further, no party solicited to participate in a block trade or otherwise involved in the negotiation of a block trade may trade on the basis of non-public information obtained through the solicitation or negotiation of the block trade prior to the public report of the block trade, except that the counterparties to a consummated block trade shall not be precluded from trading following the consummation of the block trade prior to the block trade being publicly reported.

A broker negotiating a block trade on behalf of a customer may disclose the identity of the customer to potential counterparties, including the counterparty with which the block trade is consummated, only with the permission of the customer.

11. Block Trades between Affiliated Parties

Block trades between the accounts of affiliated parties are permitted provided that 1) the block trade is executed at a fair and reasonable price; 2) each party has a legal and independent bona fide business purpose for engaging in the trade; and 3) each party’s decision to enter into the block trade is made by an independent decision-maker. In the absence of satisfying the requirements above, the transaction may constitute an illegal wash trade prohibited by Rule 534 (“Wash Trades Prohibited”).

12. CME & CBOT Block Trade-Eligible Products

For purposes of the interest rate products in the tables, the following times apply:

The Exchange shall designate the products in which block trades shall be permitted and determine the minimum quantity thresholds for such transactions. The following shall govern block trades:

J. A foreign Person performing a similar role or function to a CTA or investment advisor as described in Section I, and subject as such to foreign regulation, shall be the applicable entity for purposes of Sections A., B., C., and D., provided such Persons have total assets under management exceeding $25 million and the block trade is suitable for the customers of such Persons.
